Mobile Coverage

Abstract

In wireless sensor networks, a coverage is largely classified into three categories: area coverage, barrier coverage, sweep coverage. The area coverage is to perform a static deployment of sensors with a possible use of mobility of sensors so as to maximize the total area. The barrier coverage is to construct barriers which are able to detect penetrations of intruders. The sweep coverage is to monitor specific points of interests (PoI) periodically where the coverage at each PoI should be time-variant. This chapter deals with those coverage categories based on the mobility of sensors. Then, for each coverage, we focus on introducing various research problems and critical issues by mobile sensors including how mobile sensors can be applied to the problems in the coverage area in order to achieve specific objectives defined by systems. Also, we describe various strategies and their solutions by those novel approaches in the specific area.
